To acquaint the users of the new edition with the original spirit and methodolgy of compiling the Biographical Dictionary, we have left intact the original Introduction and the Guide to Abbreviations. Much else has been changed, added, or cut out in the remaining parts of the volume: the list of biographies, the list of pseudonyms, and the text of individual biographies themselves. To express in figures the scope of change: 35 completely new biographies have been written, escalating the total number of biographies from 718 to 753; whereas the original edition identified 358 pseudonyms, that numer is now 435; and, in 229 biographies that appeared in the first edition, several corrective or additional facts have been supplied.

The seven essays in this volume represent edited versions of original papers, expanded comments, and one public address presented on the third day of the international conference organized by the Hoover Institution on War, Revolution, and Peace at Standard University on October 5, 6, and 7, 1964, entitled "One Hundred Years of Revolutionary Internationals."
